Regression from df2bd61de6, where the
default hardened char was changed from "'" to "h". Note that there was
no corresponding wallet db upgrade, so some files use one char and
others use the other.
B023 Function definition does not bind loop variable 'already_selected_buckets_value_sum'
in keepkey/qt.py, looks like this was an actual bug
(fixed in trezor plugin already: 52a4810752 )

pity. it looked to be a neat and concise pattern.

I don't like this being hidden in the toolbar menu.
The other items in the toolbar menu are ~settings or generic actions
independent of the current request. This one is dependent on the
current request, and even the active "tab"... does not make sense
to show this when the lightning tab is active.
It is more difficult to discover it in the first place than previously,
and it being less visible goes against encouraging hw device users of
using it, which is what we should be doing.
Anyway, this commit just makes it functional as-is.
Required a much higher mental load to parse the name "convert_bip32_path_to_list_of_uint32"
than to parse "convert_bip32_strpath_to_intpath".
And we already have the ~inverse: "convert_bip32_intpath_to_strpath".
This fixes a regression where the plugin was assuming ordering for
txin.pubkeys (which is now a set).
(previously txin.pubkeys was a list ordered according to the final
sort order of keys inside the bitcoin script)
- the DeviceMgr no longer uses xpubs to keep track of paired hw devices
- instead, introduce keystore.pairing_code(), based on soft_device_id
- xpubs are now only used in a single place when the actual pairing happens
- motivation is to allow pairing a single device with multiple generic
output script descriptors, not just a single account-level xpub
- as a side-effect, we now allow pairing a device with multiple open
windows simultaneously (if keystores have the same root fingerprint
-- was already the case before if keystores had the same xpub)
This transport IIUC is only used for the trezor emulator.
The default timeout is 10 seconds. Every time we enumerate hw devices,
we also enumerate trezor devices, including scanning for the udp transport.
For some reason, recently on Windows, sporadically, this scan keeps
hitting the timeout for me. Quite annoying, as I might not even be testing
trezor (and I am certainly not testing using the trezor emulator on Windows...),
but scanning to test other plugins.
Probably overkill to have a 10 sec timeout for contacting localhost anyway.
Since Electrum is not using TxRequestSerializedType.serialized_tx
we might ask the device not to serialize transactions
by setting SignTx.serialize=False
This flag is only present in trezorlib 0.13.4, so only users on that
version will benefit from the speedup.
However, we decided to keep the minimum required version to 0.13.0,
since the newer version is not strictly required.
